Pocket Shark
The pocket shark (''Mollisquama parini'') is a species of kitefin shark in the family Dalatiidae. The species is found in deep water off Chile in the southeastern Pacific Ocean. It was the only member of the genus ''Mollisquama'', until another species, '' M. mississippiensis'', was discovered in the Gulf of Mexico. Both species are distinguished from other sharks by two pockets next to the front fins. The pockets are large, measuring about 4% of the shark's body length. Some researchers hypothesize that the pockets may excrete some kind of glowing fluid or pheromones. Etymology The specific name, ''parini'', is in honor of Russian ichthyologist Nikolai Vasilevich Parin (born 1932). Distribution and habitat The first specimen of ''M. parini'' was found off the coast of Chile in the Nazca Submarine Ridge. This specimen was an adolescent female with a total length of , taken at a depth of , in 1979. This initially suggested that the species was distributed throughout the Pacifi ...

Dalatiidae
The Dalatiidae are the family of kitefin sharks of the order Squaliformes (the term "kitefin shark" also refers specifically to the species ''Dalatias licha''). Members of this family are small, under long, and are found worldwide. They have cigar-shaped bodies with narrow heads and rounded snouts. Several species have specialized bioluminescent organs. Though eight genera are in this family, four of them are monotypic.

Mollisquama Mississippiensis
''Mollisquama mississippiensis'' or the American pocket shark is a species of pocket shark native to the Gulf of Mexico. It is the second species of pocket shark to be described. Discovery The shark was first discovered by scientists from Tulane University that were conducting a study on sperm whales in 2010. In 2013, the National Oceanic and Atmospheric Administration identified it as a pocket shark, the first to be found in its region. A previously found specimen of a different pocket shark species was caught off the coast of Chile in 1979 and was used to identify the two different species due to their differences in size, vertebrae and numerous light-producing photophores. Description The head is bulbous, resembling that of a whale. The shark is very small, at only . Near the gill A gill () is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, hav ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Gulf Of Mexico
The Gulf of Mexico ( es, Golfo de México) is an oceanic basin, ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexico, Mexican States of Mexico, states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatan, and Quintana Roo; and on the southeast by Cuba. The Southern United States, Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are often referred to as the "Third Coast" of the United States (in addition to its Atlantic and Pacific Ocean, Pacific coasts). The Gulf of Mexico took shape approximately 300 million years ago as a result of plate tectonics.Huerta, A.D., and D.L.
